Title: Synthetic Aluminosilicate Catalyst
IPC: B01J20/18
Filed: 1966-06-21
Abstract: 1,155,282. Cracking catalysts. AMERICAN CYANAMID CO. 21 June, 1966 [8 Nov., 1965 (2)], No. 27650/66. Heading B1E. [Also in Division C1] Cracking catalysts comprise zeolite X or Y which has been treated by a novel process to reduce its alkali metal cation content to less than 2 wt. % (based on the zeolite). This process consists in base exchanging an alkali metal form of zeolite X or Y with non- alkali metal cation in two stages separated by a calcination step, said non-alkali metal being a rare earth. metal or metals (i.e: Ce,La, Pr Nd, Il(Pm), Sm, Eu, Gd, Tb, Dy Ho, Er, Tm, Yb. Lu, Y) -in the first exchange stage, and preferably also in the second. The second exchange stage may alternatively be effected with an ammonium salt alone or in combination with rare earth metal salts. The incorporation of the zeolite into an oxide matrix takes place after the second exchange stage, or less preferably after the second exchange stage in which latter event the calcination and second exchange stage are effected on the thusobtained composite. The oxide matrix may be. silica-alumina, silica-magnesia, or silicaalumina-magnesia and should itself be substantially free from alkali metal ions. In a specific Example (3) sodium zeolite Y is treated as above to reduce its Na 2 O content to 1.25% and is then blended with washed 13% Al 2 O 3 -SiO 2  cracking catalyst and spray dried to yield a catalyst containing 5% of the zeolite.

Title: Process for the pyrolitic cracking of hydrocarbon oils
IPC: C10G9/00
Filed: 1960-08-11
Abstract: Unsaturated C2-C4 hydrocarbons are obtained by the pyrolysis of hydrocarbon mixtures with a hot gas or vapour, e.g. steam, wherein the starting hydrocarbon mixture which contains unevaporable constituents is used as quenching fluid, together with water if desired, to chill abruptly the pyrolysis effluent and evaporate evaporable constituents of the starting material, thereby separating unevaporable constituents, the gas-vapour mixture is cooled to condense the starting material and the condensate is charged to the pyrolysis zone.  High-boiling or solid residues from the cracking are removed from the quenching zone with the unevaporated starting material; part of this liquid, together with a separate oil if desired, may be recycled to the quenching zone as a washing liquid. Constituents of the starting material which might not be condensed from the gas-vapour mixture may be removed prior to charging to the quenching and added to the condensate.

Class 87(ii) When a mould table 5 is intermittently rotated to bring a mould 8 under a hopper 1, an abutment 14 on the table' engages a lever 15 which operates a hydraulic mechanism 22, 23 to cause a ram in the hopper to move down and force clay into the mould. A spring maintains the valve in a a valve 26, through a chain and spring 37, to supply fluid to cylinder 23 to lift the ram rod 2a through a linkage 16, 18. Clay is then automatically fed from a mill 3 into the hopper beneath the ram. This upward movement of the ram rod 2a operates the valve, through a chain 34, to supply fluid to the cylinder 22, which causes the ram to move down and force the clay into the mould. A spring maintains the valve in a rest position, see Fig. 2, (not shown), when the machine is not in use. The mould is pressed into engagement with the hopper during filling by a cam rail 11 which engages a roller 7 connected to a carrier 7 for the mould. The lever 15 is so shaped that it prevents the mould from moving in one direction.

Title: Improved method of, and means for, the manufacture of chain
IPC: B21L3/00
Filed: 1934-10-02
Abstract: 445,038. Soldering chains. WILKINS & WRIGHT, Ltd., and HEWITT, J. H., Holyhead Road, Handsworth, Birmingham. Oct. 2, 1934, No. 28228. [Classes 83 (ii) and 83 (iv)] In soldering or brazing chains of the kind in which some or all of the links consist of looped wire or strip, the chain is conveyed endwise, the links arranged to extend transversely of the feed direction with joints directed outwardly, the joints fed with solder and soldering effected by heat, the arranging, feeding and soldering steps being effected while the chain is in motion. The chain 19 is fed through adjustable guides 18, then through a preheater 32 and then under a soldering burner 30, on a chain conveyer which is traversed by chain and worm gear 29 from a belt or electric motor in a slot in a bench 12. The chain conveyer consists of a pair of spaced chains 14 supporting small platforms 15 arranged in end to end contact. Before the chain reaches the guides the links are manually arranged with the joints of alternate links on opposite sides of the chain, and solder is applied either by hand or automatically. The guides urge adjacent links uniformly into oppositely inclined positions so as to clear the joints and prevent the links from being soldered together. The preheater may consist of a chamber 32 lined with asbestos &c. and heated by the soldering burner, or the chamber may contain a separate burner. The chain is retained in pressure contact with the conveyer by a roller 37 on a weighted or spring- pressed lever. The conveyer, which may be tensioned by a jockey pulley is cooled by air &c. blown through a pipe 39. The chain may be fed by separate conveyers during the solder applying and soldering operations.

Title: Hydraulic copying device for lathes
IPC: B23Q35/18
Filed: 1950-11-20
Abstract: 684,439. Copy-turning. FISCHER AKT.- GES., G. Nov. 20, 1950 [Dec. 2, 1949], No. 28349/50. Class 83 (iii). In a copying lathe, the position of the tool 12 or the tool 25 is controlled by a follower 19 engaging a template 26 or 78. The follower acts through a valve 16 which controls the supply of fluid pressure from a pump 22 to either side of a piston 8 attached to the saddle 6. A cylinder 9 forming the tool-slide is thus moved as described in Specification 652,537. The initial position of the tool-slide is set by a screw 14. The follower 19, carried on a pivot 20, is biased towards the appropriate template by a spring 17 or by a spring 33 acting through levers 28, 30. If the tool 12 is to cut, the lever 30 is rendered inoperative by movement of a handle 35 which moves a link 41 to compress the spring 33. The spring 17 then moves the valve 16 so that the tool-slide moves upwardly until the follower 19 engages the template 26. Conversely, movement of the handle 35 to its second position causes the spring 33 to move the lever 28 and hence the valve 16 until the follower 19 engages the template 78 and the tool 25 is brought into operation. The limits of movement of the slide 9 are determined by stops 47, 49 which are adjusted by wheels 51, 54. Thus, if it is desired to withdraw the tool 12 at a predetermined position, a stop 57 on a bar 56 carried by the machine is set to strike the lever 36, and so cause the slide to move away from the work until arrested by engagement of the lever 28 with the stop 49. A cylindrical surface can be turned by setting the lever 35 in its upper position and setting the stop 47 to engage the lever 28 and render the follower inoperative. The tools 12, 25 are used in combination so that the upper tool may cut the portions 82. In the event of a failure in the supply of fluid, downward movement of the slide is checked by a fixed stop 80 engaging the stop 49. If the tool 12 is to cut in several passes, the position of the stop 47 is adjusted in steps by the hand wheel 51 which carries adjustable stops coacting with a stop 67. The apparatus may be modified to turn internal contours. Specification 579,611 also is referred to.
